OTFT – Transistors

Organic Thin Film Transistor (OTFT) technology involves the use of semiconductor organic compounds in electronic components, especially computer displays.

Applications in OTFT

Organic substrates allow displays to be manufactured on flexible surfaces, rather than rigid materials, as is necessary in traditional TFT displays. A piece of flexible plastic can be coated with OTFT material and made into a screen that can be handled like a paper document.

Great potential for a wide variety of applications, especially for new products that rely on their unique characteristics, such as electronic newspapers, inexpensive smart tags for inventory control, and large-area flexible displays.

Advantages

• Cost. Organic screens have always been relatively cheap but were slow in terms of wearer mobility. This slow mobility of the wearer means a slow response time, which limits the ability of a screen to represent movement. However, new research has developed a process to grow organic crystals with carrier mobility that rivals that of traditional TFT materials.
• Flexibility. The mechanical flexibility of organic materials makes them naturally compatible with plastic substrates for lightweight and foldable products.
• Fabrication. Their fabrication processes are much less complex compared with conventional.
